The arches 19 are SO. constructed that yustvsuiiicient room isprovided to permitof ypassage ot' theico'tton plants of the.y rowitherebetween and accordingly the inner edge walls 12 of the pan `will bearranged in. closepronimity tothe plants. The superstructureas repret sented by the arches 19. andthe covering Ytogetheruwiththea-rms 24: will ,be` main@ tained in substantially,verticalfpos'ition at/ alltimes by the` plants and sincethe arms of the arches 19 are'rigidlyconnected with the inner edgesfofthepans, thes`e`-'V inner f edges offtlie 4pans will' likewise be',Y maintained in substantially vertical position and at 4all times 'in 'close engagement with the.

stalks of the plants, thereby leaving but a slight space *between Vthe adjacent. edgesy of, the Vpan through which weevils may fall to the ground. r'The liook and slot engagement of thelower endsgof the arms witlithe outer edges of the pans permits vthese pansl at l 1 allitimesto maintain Vaclose engagement with the ground, allowing these vouter edges torise aiidfall tor compensate for ridges or hollows in which thel cotton plantsniay lie'.A

Accordingly, the diagonal 'stv-rips, *18 are at all times closelyi engaged withthe'fground veso and engagethe same from thebasejofthe plants to a-point approximating the center of Vthe middle between the rows Yand yall loose articles upon the-ground, such as" dead Y squares, weevils 'andthelV like, will accordingly 'be swept frombeneath the rplantstof a point at thecenter of the row. In order `Each arm hassecuredtliereto'adrjacent its lower end an inwardly v extending `to providek for the destruction 4of'weevils and squares thus forced'to the center of ythe row, l provide Aheavy bull' or ytracker wheels '2G following the outer edges of the pans immediately urearwardly thereof andv passing above articles discharged from the outer edgeof the'diagonal strips 18 to crush and destroy the saine..
